PRODUCT DESCRIPTION
AMSOIL High Performance Synthetic 20W-50 Motor Oil is specifically
formulated to provide tough lubricating protection in the most
demanding operations. It is recommended for use is motorcycles,
pickup trucks, recreational vehicles and other high-stress vehicles
powerd by gasoline or diesel engines. AMSOIL SAE 20W-50 High
Performance Synthetic Motor Oil may be used in all motorcycle engines,
including those with a wet clutch system, requiring an API CD, SG-CG
or SH-CD oil.
WEAR PROTECTION
The AMSOIL High Performance Synthetic 20W-50 Motor Oil anti-wear
additive package contains high levels of zinc and phosphorous for
superior protection of cam lobes and other high-pressure parts.
In fact, AMSOIL High Performance Synthetic 20W-50 Motor Oil contains
more zinc and phosphorous than most
popular motorcycle manufacturer motor oils. Its superior
anti-wear
package offers superior wear protection. AMSOIL High Performance
Synthetic
20W-50 Motor Oil leaves a wear scar up to 40 percent smaller than the
scars
left by other popular brands in the ASTM D4172 Four-Ball Wear Test.
Some motorcycle transmissions and engines share an oil sump, so the
engine oil also provides wear protection to the transmission
gears. AMSOIL High Performance Synthetic 20W-50 Motor Oil offers
superior wear protection to transmission gears, which are often
subjected to high surface pressure and rotation speed. It also
promotes proper wet clutch performance.
FRICTION MODIFIER FREE
AMSOIL High Performance Synthetic 20W-50 Motor Oil contains no friction
modifiers, making it ideal for motorcycle engines. The friction
modifier free formulation of AMSOIL High Performance Synthetic 20W-50
Motor Oil ensures dependable starting, smooth running, good fuel
efficiency, desirable stall speeds and clutch compatibility.
DIESEL FORMULATED
AMSOIL High Performance Synthetic 20W-50 Motor Oil contains a robust
dispersant/detergent additive package, making it ideal for use in
high-stress
diesel engines. Its 12+ TBN ensures lasting protection against
acid
and soot in high-stress diesel applications. In fact, its
dispersant/detergent
additive package is a proven extended drain lubricant.
TEMPERATURE AND PERFORMANCE
AMSOIL High Performance Synthetic 20W-50 Motor Oil offers the superior
protection and lubrication at high and low temperatures found only in
top-quality synthetic oils. Its outstanding low temperature
fluidity ensures easy cranking, dependable starting and fast
post-startup protection. Its superior high-temperature protection
ensures the formation of a clean, protective film of oil between
working parts during high-temperature, high-stress operations.
High-temperature operations often lead to the thermal degradation
and oxidation
of conventional oils, which leads to the formation of deposits, sludge
and
varnish. AMSOIL High Performance Synthetic 20W-50 Motor Oil
withstands
thermal degradation and oxidation at higher temperatures than
conventional
oils do, ensuring clean, dependable performance in high-stress, high
temperature
operations.
